/**

 * <ul>
 * <li>a list of criteria an HAL object must match,</li>
 * <li>a <code>deviceAdded()</code> method that will be called when a
 * DeviceAdded signal is received about an HAL object that matches the criteria,
 * </li>
 * <li>a <code>deviceRemoved()</code> method that will be called when a
 * DeviceRemoved signal is received about an HAL object that matches the
 * criteria.</li>
 * </ul>
 * See the V4LHalFilter class in the examples package.
